To all whom it may concern:

Be it known that I, JAMES J. Ross, residing in Milwaukee, in the countyof Milwaukee and State of Wisconsin, have invented new and usefulImprovements in Combination-Ovens, of which the following is adescription, reference being had to the accompanying drawings, which area part of this specication.

This invention has for its object to provide a portable oven for gasranges and the like which will be provided with removable and adjustableparts permitting it to serve various purposes such as for baking,broiling, toasting and for conveying heat-ed food from place to place.

With the above and other objects in view the invention consists in thecombination oven herein claimed, its parts and combinations of parts andall equivalents.

Referring to the accompanying drawings in which like characters ofreference indicate the same parts in the different views- Figure l is aperspective view of the combination oven of this invention with the hoodwithdrawn from the base and the various slides in partially withdrawnpositions to suggest their removability; Fig. 2 is a transversesectional view of the oven in condition for baking; Fig. 3 is a similarsectional View thereof on a plane at right angles to the sectional planeof Fig. 2; Fig. 4 is a frontelevation of the oven; Fig. 5 is aperspective view of the plain bottom for use when the oven is employedfor conveying food' from place to place or for heating irons or thelike; Fig. 6 is a perspective view of the deflector for use when theoven is employed for baking; and, Fig. 7 is a bottom view of theremovable bottom ordinarily used with the oven showing the perforatedplate thereof partially withdrawn.

In these drawings 10 indicates a base or body portion of the oven,preferably composed of sheet metal formed upon an angular wire frame l1which has the front and top edges of the side pieces of the base and thetop edge of the back piece turned thereon so that the base consisting ofsaid back piece and the two side pieces is braced and made rigid by theheavy wire frame and the said side pieces have their front edges held infixed position with relation to each other by said wire frame 11connecting them near their lower ends as shown in Fig. 1. The loweredges of the side pieces and the back piece of the base or body portion10 are bent outwardly and then upon themselves to form guide grooves fora bottom plate 13 which is slipped in place therein from the front asshown in Fig. l, said bottom plate passing just beneath the portion ofthe wire frame l1 which connects the side pieces of the base 10. Thebottom plate 13 in turn is provided with a central opening with guidegrooves 14C formed at its edges to receive a perforated sheet metalplate 15 which slips in place therein from the front.

'1`he side pieces of the base l() have inwardly extending supportinglugs 16 struck up therefrom which form ledges at different elevationsfor supporting wire frames or racks 17 at different distances from thebottom plate and also for supporting a deflector 18. The deflectorcomprises a sheet metal top plate somewhat larger than the opening inthe bottom plate 13 but smaller than the area of the base so as to leavea space entirely surrounding it, said plate having its edges turned overa wire frame 19 which is of a shape to t upon the lugs 16 and properlyspace the plate above the opening in the bottom plate, and a V-shapeddeflecting plate 20 beneath the supporting plate to deflect the hot airand gases enter ing through the opening in the bottom plate toward eachside of the oven, a sheet of asbestos or other heat insulating material21 being preferably mounted beneath the supporting plate as a liningtherefor, as shown in Fig. 3.

A hood 22 of a shape and size to neatly lit over the base or bodyportion 10 is provided and the main portion of the front of said hoodconsists of a downwardly swinging door 23 which may be locked closed inthe usual manner and through which access may be had to the interiorwhen the hood is in place upon the base. A handle 24 1s formed on thetop of the hood for convenience -in handling it and pivoted catches 25are provided at the lower edge of the hood to engage beneath the base 10as shown 1n Fig. 2 and lock the hood and base together. The pivotedcatches as here shown are 1n the form of wire hooks pivotally mounted incleats on the sides of the hood and having spring handles bent to bearagainst the front of the hood with pressure where they ride over studsor projections 26 in the front of the hood, preferably formed byindentations on the inner side thereof, as shown in Fig. 3,

and in this manner the catches are locked in their open or closedposition.

A sheet metal supplemental bottom plate 13 may be substituted for orassociated with the bottom plate 13 by sliding it in the guides 'l2 andit is without the central opening of the bottom plate 13, having insteada series of perforations 27 around its edge. In practice the bottomplate 13 is usually employed and when it has its perforated plate 15removed and the deflector 18 is in place above the opening` as shown inFigs. 2 and 3 with the hood placed over the base the device constitutesan oven for baking, the baking pans being placed directly upon the upperplate of the deflector or upon the racks 17 in position thereabove. Thebaking pans may be inserted or removed at will by opening the door 23.The hot air from the flame below will enter the oven through the openingand will be thrown to all sides of the oven by the defiector so as touniformly heat the entire interior of the oven` the air space formedbetween the walls of the base and the hood serving to assist inretaining the heat within the oven. With the deilector removed and theperforated plate 15 in place, as shown in Fig. 1, the oven is adapted toserve for toasting, the perforated plate preventing the scorchingof thematerial being toasted and the distance of the material from the flamebeing regulated by raising or lowering the supporting racks 17. Thetoasting may be performed with the hood in place, when access may be hadto the interior through the door, or the hood may be removed and thetoasting performed on the base portion alone. By leaving` the deflectorout and removing the perforated plate 15 the oven may be used forbroiling, the meat or other material to be broiled being placed upon theracks 17 nearer to or farther from the flame which has free accessthereto through the opening in the bottom plate 13. By substituting` thesupplemental bottom plate 13 for the bottom plate 13 the oven may beused for heating sad irons or the like, which may be inserted andremoved through the door opening, the deflector and racks being removedat such times. ln this condition of the oven it is also adapted forcarrying food from place to place, the openings in the bottom.permitting of ventilation thereof without a material loss of the heat.
